Five hundred tickets were sold for a recent music concert. The upper deck seats, u sold for $37.50; the regular seats, sold for $58.50; and the floor seats, sold for
$77.00. The total revenue for the concert was $28,450. There were twice as many
upper deck seats sold as the sum of regular seats and floor seats.
Which system of equations can be used to determine how many of each seat were
sold?

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

600,000,000,000, or 6e14
